How do i remove the fan clutch on my 1995 BMW 325i
You have to purchase or make a tool to hold the pully stationary as you unscrew the fan from the water pump shaft. I bought a strap of steel 1/8" thick and 1 1/2" wide and 24" long at the hardware store. I then drilled two holes in it close to one end, and close to one side of the strap. The hole diameter is just big enough to fit over the heads of the 10 mm bolts that hold the pulley in place. Note that the bolts are in a rectangular pattern. It is best to space your holes to fit two bolts that are the long side of the rectangle. Then I had to grind a half-moon shape into the side of the strap between the holes to allow for the shaft so the tool would get close enough for my little holes to fit over the bolt heads. If this is unclear, you should be able fine a picture of the tool on an automotive tool website.
Then I use a crescent wrench with extra narrow jaws to turn the nut on the fan clutch that screws onto the water pump shaft. This is a lot easier if you remove the air filter box so you can get to that nut easily.
Most important - that nut that holds the fan clutch on the water pump shaft is LEFT HANDED THREAD. Turn it clockwise to unscrew it.
